Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 7-1879062-9 are identified based on strict electrical and mechanical parameter matching. All substitute candidates maintain the following core specifications:

Critical Matching Parameters:

• Capacitance: 0.68 µF (exact match required)
• Voltage Rating: 35 V (exact match required)
• Tolerance: ±10% (exact match required)
• Package: 1206 (3216 Metric) surface mount (exact match required)
• Type: Molded tantalum (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Performance Variation Parameters:

• ESR values range from 4Ohm to 8Ohm across substitute options, representing acceptable performance variation within the molded tantalum capacitor category
• Packaging format varies between bulk and Tape & Reel (TR) configurations, accommodating different procurement and assembly workflows

All identified substitutes are active products with current manufacturing status, ensuring long-term availability and supply chain continuity. Compliance certifications (RoHS3, REACH Unaffected, EAR99) are maintained across the substitute group, with one exception noted in the detailed comparison table.

Parameter Comparison

Engineering Selection Recommendations

Direct Electrical Equivalents (ESR 6Ohm):

TPSA684K035R6000 and TPSA684K035Y6000 from KYOCERA AVX provide the closest electrical match to the original 7-1879062-9, maintaining identical 6Ohm ESR specifications. Both parts are active products with ROHS3 compliance and Tape & Reel packaging. These parts are recommended as primary substitutes for applications where ESR performance is critical to circuit operation.

Lower ESR Alternatives (ESR 4Ohm):

593D684X9035A2TE3 (Vishay Sprague) and TR3A684K035C4000 (Vishay Sprague) offer reduced ESR at 4Ohm, providing improved high-frequency performance and lower impedance characteristics. Both are active products with ROHS3 compliance. These options are suitable for applications requiring enhanced transient response or reduced ripple current effects.

Higher ESR Alternatives (ESR 7.6Ohm to 8Ohm):

T491A684K035AT (KEMET), TAJA684K035RNJ (KYOCERA AVX), TAJS684K035RNJ (KYOCERA AVX), and 293D684X9035A2TE3 (Vishay Sprague) feature ESR values ranging from 7.6Ohm to 8Ohm. All are active products with ROHS3 compliance except TAJA684K035K, which is RoHS non-compliant. These options are acceptable for general-purpose applications where ESR tolerance is within acceptable circuit margins.

Physical Considerations:

TAJS684K035RNJ features a reduced seated height of 0.047" (1.20mm) compared to the standard 0.071" (1.80mm) height of all other options. This part is suitable for space-constrained applications with low-profile PCB requirements.

Compliance and Availability:

All recommended substitutes maintain REACH Unaffected and EAR99 classifications consistent with the original part. ROHS3 compliance is achieved across all active substitutes except TAJA684K035K. Current inventory levels range from 620 to 25,100 pieces, ensuring supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can I substitute the obsolete 7-1879062-9 with any of the listed parts?

A: All listed substitute parts maintain identical capacitance (0.68 µF), voltage rating (35 V), tolerance (±10%), package (1206), and operating temperature range (-55°C to 125°C). Physical and electrical compatibility is confirmed for all substitutes. Selection should be based on ESR requirements and compliance specifications for your specific application.

Q: What is the significance of ESR differences between substitute options?

A: ESR (Equivalent Series Resistance) affects high-frequency performance, ripple current handling, and transient response. The original part specifies 6Ohm ESR. Substitutes with lower ESR (4Ohm) provide improved performance in noise-sensitive or high-frequency applications. Substitutes with higher ESR (7.6Ohm to 8Ohm) are acceptable for general-purpose applications where ESR tolerance is within circuit design margins. Verify ESR requirements in your circuit design before selection.

Q: Are there packaging format differences I should consider?

A: The original part is supplied in bulk format. Most substitutes are available in Tape & Reel (TR) packaging, which is standard for automated assembly processes. TAJA684K035K is available in bulk format. Tape & Reel packaging is recommended for high-volume production. Confirm packaging compatibility with your procurement and assembly processes.

Q: What is the difference between TAJA684K035RNJ and TAJS684K035RNJ?

A: Both parts are from KYOCERA AVX TAJ series with identical electrical specifications (0.68 µF, 35 V, ±10%, 8Ohm ESR). The primary difference is seated height: TAJA684K035RNJ has a maximum height of 0.071" (1.80mm), while TAJS684K035RNJ has a reduced height of 0.047" (1.20mm). Select TAJS684K035RNJ for applications with low-profile PCB constraints.

Q: Is RoHS compliance required for my application?

A: ROHS3 compliance is achieved by all active substitutes except TAJA684K035K, which is RoHS non-compliant. If RoHS3 compliance is a requirement, exclude TAJA684K035K from consideration. All other substitutes meet ROHS3 standards.

Q: Which substitute offers the best overall compatibility with the original part?

A: TPSA684K035R6000 and TPSA684K035Y6000 from KYOCERA AVX provide the closest match, maintaining identical 6Ohm ESR, standard 0.071" height, ROHS3 compliance, and active product status. These parts are recommended as primary substitutes when ESR performance equivalence is required.

Q: Can I use these parts interchangeably in existing designs?

A: All substitutes maintain identical capacitance, voltage rating, tolerance, package, and operating temperature specifications. Physical footprint compatibility is confirmed for all parts except TAJS684K035RNJ, which has reduced height. ESR variations (4Ohm to 8Ohm) may affect circuit performance in noise-sensitive applications. Verify ESR compatibility with your circuit design specifications before implementation.

Q: What inventory levels are available for these substitutes?

A: Current inventory ranges from 620 to 25,100 pieces across the substitute group. TAJA684K035RNJ offers the highest availability at 25,100 pieces. Confirm specific part availability with your supplier for production planning purposes.
